LEED Green Associate (LEED GA) — Question 85

As of 1996, the Montreal Protocol banned the production of what chemical compound known to have ozone-depleting potential?

Answer options

• A. Chlorofluorocarbons (CFCs)
• B. Hydrofluorocarbons (HFCs)
• C. Hydrofluorocarbons Phaseout Management Plan (HPMP)
• D. Hydrochlorofluorocarbons (HCFCs)

Correct answer: A

Explanation

The correct answer is A, Chlorofluorocarbons (CFCs), as they were identified as significant contributors to ozone depletion and were banned under the Montreal Protocol. Options B and C are incorrect because Hydrofluorocarbons (HFCs) were not banned by the protocol, and HPMP is a plan related to HFCs, not a compound itself. Option D, Hydrochlorofluorocarbons (HCFCs), was phased out later, but it was not the primary focus of the 1996 ban.
